0 all tlf/i022? it may concern: lie it known that l, ('r'ro BALLERL a citizen of the German Republic, and residing at Berlin, Germany, have invented a certain new and use-ful improved Car-Body-rlp` ping Device, of which the following is a speciiication.

My invention relates to a tip-car of the type known as universal tip-car, the body of which can be tipped rearwardly, as well laterally by means of only one tipping device.

r'here are, among the tip-cars of this known type, also such where the tipping member proper consists or" a rack engaging the car-body below its centre of gravity, the rack being actuated by a cog-wheel gearing and this latter, together with a casing enclosing` it, and with saidrrack, bein r` so arranger and supported as to be able to ascillate on a driving spindle lyingparallel to the longitudinal axis or" the car.

rlhe object ot the present invention is to obviate a certain difficulty connected with car-body tipping devices of the before-mentioned kind, viz. such with rack and cogwheel gearing, especially it the car is driven by the intermediary ot' .a Cardan-gear. It is, with tip-cars of this kind very diiiicult to house the rack, or racks, in such a manner that it does not, or they do not, intertere with the Cardan-shaft or with parts pertaining thereto. rllhis ditriculty is obviated in the present invention by using a ste-called double-jack instead oi the simple rack-jack hitherto employed, the car-body li'i'fiingmember oi? the double jack being devised similarly to a crank-drive gearing or to a vconnectin,f ,'rod gearing, and the crank or the connecting rod being actuated by a cog-wheel, or by a plurality of cog-wheels. rlhe shaft, or shafts, ot' the cog-wheels` as the case may be, move, up or down simultaneously with the revolution of the cog-- wheel which is. accomplished by means ot a. pinion connected firmly with the shaft of `the crank cogswheel, which meshes with the teeth of a rack and moves it up or down according to the direction of rotation of said crank cog-wheel.

My invention is illustrated by way of example in the accompanying drawings in wiich Figure l is a side-view of the rear part of a motor freight tipping car provided with the improved tipping device, the

car-body being shown in two positions, viz. in its normal position in full lines, and rearwardly tipped in dottedlines; Figure 2 is a rear view of said car, the body being also in this gure shown in two positions, v'z, in its normal position in full lines, and tilted laterally in dotted lines; Figure 3 is a side-view of the tipping device proper', dra-wn to an enlarged scale, the position ot the uppermost parts of the iigure (portieriv oi the car-body bottom andpa-rts aiiixed thereto and connected therewith) corresponding to the position shown in dotted lines in Fig. l; Figure 4 Vshows'the same parts in the position corresponding to that shown in full lines in Fig. 1; Figure 5 is a front-view of the same parts, and Figure 6 is a plan thereof.

l, Figs, l and 2, denotes the body of the car, and 7, Figs. 3-5, thebottom thereof, to which is-secnred a body frame 6 carrying a eonneeti'ifigV trame 4 provided with pivots 5 on which the'frame 6 (with thecar-body) can turn to one or the other side (Fig. 2, position shown in dotted lines) .i The trame 4 is connected to the upper ends of connecting rods 2 (Figs. 3-5), but this connection is an indirect one in that it is eii'ected by the intermediary .of springs 26 connected at their ends by bolts 27 with the trame 4, and connected with the rods 2 by bolts 25 located in short vertical slots 4a (Fig.` 5) ot the side-parts of the frame 4. The upper end of each connecting rod 2 engages a vertical slot 4b, the size of which is such that the rod 2 can assume an oblique position relatively to the frame 4, as shown in Fig. il. But the rods 2 can also `be moved a trifle relatively to the slots 4, that is to say, the bolts 25 can be moved a little up or down therein, as the case may be, the springs 26 being then slightly bent so as to turn from' their straight. shape (Fig. llinto a slightly curved one (Fig. 4), or reversely.

There are two connecting rods 2, one on the lett or" the frame 4, they other on the right thereof (Figs. 5 and 6), and each rod 2 is connected with a large cog-wheel 9 by means ot a crank-pin 8. The two cogwheels 9 are firmly connected with each other by an axle lO, to which is firmly secured a smaller cog-wheel ll meshing with a rack l2 hingedat the point 13 toa frame 14 which has a pivot 23 at its front end and a pivot 25 at its rear end, the two pivots being supported intransverse members 22 forming parts ofthefsuper-structure of the car. The jack frame 14 serves also as carrier of a casing enclosing some of the parts formingl the cog-wheel gearing.

The rack 12 is held in gear with the cogwheel 11 by a sleeve l5 having a "lateral extension enclosing the cogwheel 11. The mechanism consisting of the cog-wheel '9, the` cogwheel 11, the'axle 10, `and the sleeve 15, caribe moved upand down along the rack;1 2 (compare Figs. y3 land4) and issupported in every position b two arms 16 supportedwith their free en ys onlan axle 17 of a driving cogr-wheelrlSwhich is constructed asa worm-.wheel andmeshes with a worm 18a (shown inFigs. .4.-6 in dotted lines) securedtothe driving shaft 24 which extends into thejgearing through the pivot 23 that is provided with aborefor thispurpose. v

On the axle or shaft 17 are two pinions` -which mesh with thelarge cogfwheels 9 at any position of height ofpthese latter (Figs. 3 and 4). owing-to the connection of the axle or shaft 17 with the axle 10 by the Y arms 16.

The manner of operation of tlietipping device vis as follows:

Supposing,the car-body be in its proper `normal or horizontal position, Aas in Figures v1 and 2,(position shown in` full lines) and shall bel tipped if rearwardly or laterally, the shaft --24,is. coupled xwiththe motor of the carlb'y fmeansl of a friction-clutch orany otherv suitable clutch, lin consequence whereof theworm-gearing-lS /18 isrotated, as `are, of course, also. the shaft 17, the pinions 20, the large cog-wheels 9, the axle 10, and the Y cog-wheel 11,:so that` this latter climbsup- ,as theA case may be. -Tippingthe'car-body laterally is Arendered possible by the provi-sion of the frame 14 withv its` pivots 23 and 25. whichare situated ust in the longitudinal ,axis ofthe car (Fig. 2,).

Thefsuccession of the motions is, ofcourse,

Vthe reverse ywhen the car-body is moved back into its initial` position. `When it has arrived in itsinitial position, the crank-pinsS `are in theirflowermost position, and in this position thesprings 26 are slightly'bent. down -so that the car-body is drawn or pressed onto its supportswith a certainpower whereby it is retained securely in its' position of rest.

' wardly extending rack hinged to said frame; a cog-wheel meshing with said rack; means to keep thelatter Vconstantly in meshV with said c.ogwheel; an axle connected vfirmly with the said cog-,wheel and extending to both sides thereof; Ytwo vlarger cog-wheels secured to the ends of said axle and connected firmly therewith two connecting-rods hinged at theirlower ends to saidrlarger cog-wheels and at their upper ends to the car-body; means for carrymgthe said .axle with its Vcog-wheels, and means i`ior4transrr`1itting motion to the said two `larger cogwheels.
